What the register lists it for
These are the uses the European Commission’s CosIng register lists for Crambe Abyssinica Seed Oil in any cosmetic, hair roles first. They say why a maker might add it, not what it does in one formula, and they aren’t a safety rating.
- Hair conditioning
-
The register’s hair role for ingredients that make hair feel softer, smoother or easier to comb. Most conditioners, masks and leave-ins list several.
Register definition: “Enhancing the appearance and feel of hair. Leaving the hair easy to comb, supple, soft and shiny and/or imparting volume, lightness, gloss, texture, etc.”
- Emulsion stabilizing
-
Keeps a cream’s oil and water from separating on the shelf.
Register definition: “Helping the process of emulsification and improving emulsion stability and shelf-life.”
- Occlusive
-
Forms a layer that slows water loss. Heavier oils, butters and waxes carry it.
Register definition: “Retarding the evaporation of water from the skin surface. Occlusives are generally lipids which tend to remain on the skin surface and thus increase the water content of skin.”
Where it sits on each label
US labels list ingredients from most to least, except that those at 1% or less may follow in any order. A name near the top is a large part of the formula. A label doesn’t mark where the 1% point falls, so further down, the order says little about how much is in it.
- Shampoos 1 label First five names: 0 of 1 Shampoos without it
- Rinse-out conditioners 1 label First five names: 0 of 1 Rinse-out conditioners without it
- Deep conditioners 1 label First five names: 0 of 1 Deep conditioners without it

- OLAPLEX No.5 Bond Maintenance Strengthening Conditioner Rinse-out conditioner 24th of 66 names
- Mielle Babassu & Mint Deep Conditioner Deep conditioner 27th of 38 names
Each line runs from the first name on a label to the last; a dot is where this ingredient sits. Makers change formulas now and then; if the list on your bottle differs, go by your bottle.
